On most servers I’m responsible for, I use to compile my own kernels. Instead of downloading/applying patches, which is cumbersome, I was using the (now broken) mercurial mirror http://www.kernel.org/hg/linux-2.6 It was great as i just had to do something like “hg pull -u; hg up -r v2.6.xx” to update my tree. Though, this has several […]

I’m still using this small utility that displays the activity of ’emerges’ on the misc gentoo boxes I’m admin for. I’ve wanted to add a graphical interface for very long, but did not have the time… until recently. So here it is. It is available for download from the homepage and as a mercurial clone.

As time goes, my mercurial ‘activity’ plugin has got more and more options. Useful and requested options of course, but still it kinda clobber the –help output and it is more and more cumbersome to play with. This is why I have introduced a new frontend, based on Qt, to play/decide about those options. First, […]

It is easy to find information on how to detect the availability of the different SSE instructions sets on the x86 platform.. but this get trickier when you’re looking after AltiVec.

Well… you know how it is, you get used to a tool, and even if some brand new software is now available, you keep on using this old stuff. In his case, i’m speaking of xv, whose last release was in 1994. It’s still my default viewer for all image formats in my KDE/firefox/whatever settings. […]

You might know that there’s a new kid in the C++ compilers list ; clang. Llvm has been around for quite some time, but until recently the only way to make use of it was through the somehow cumbersome llvm-gcc which binds the gcc C/C++ frontend to the llvm backend. People (mostly Apple) have been […]

qmake (sort of) supports lex/yacc, but modern people prefer to use flex/bison. If you google, you can find some tricks like convincing qmake that yacc is spelled ‘bison’ and so on.  Morever qmake supports for lex/yacc has several drawbacks, such as weird naming scheme, and (when using the tricks), dependencies are not building files in […]

One could think that this is as easy as crossdev avr but it is not, so i write here how I did it for future reference, and hopefully this will also be useful to other people. The first problem is that it does not check compatibility between toolchain members (binutils, gcc, …). Understandably, this is […]
